If the battery and cables check good, then I would inspect and clean your main rotary ignition switch..
If by the speedo "goes dead" you mean the MPH drops to zero.....
Have you noticed that your turn signals are not cancelling .....??
FWIW... Speedometer failing, and dying when you pull in the clutch to stop, are two of the three classic symptoms of a bad VSS (vehicle speed sensor)... The turn signals not cancelling are the third...
You can pull it and try to clean it... If it has a bunch of metal filings on it, sometimes cleaning it works... but if the VSS is bad, it will need to be replaced. I hear it doesn't always throw a trouble code...
Another cause of stalling could be a dirty IAC (Idle Air Control).... but that won't affect the speedo...
Let us know what your find...

Another possibility of the stalling engine is your clutch and/or clutch cable could need adjustment. Plenty of youtube videos show the proper way to adjust those. Its pretty simple and you dont need any special tools.

EFI requires a higher idle then old carburetor motors just to keep a idle. However, you sound like you have more then one problem.
Could be a simple bad battery or connection at battery. Start there. Good fresh fuel?
If opening the throttle slightly helps the stall, it's usually fuel or a fuel filter. Is maintenance up to date? Bike stock or is a aftermarket tuner on it?
PS , just as a suggestion, make your next new post over in the new member welcome area and say helo

Does all the power cut out? I had bad ignition switch do this, when riding it probablly missed a beat and I didn't notice. But when coasting to stop it died.
Need to look at all that is going on. Head light out? Or just speedo losing signal?
